Not really. I'm just saying it out of convenience because that is how I personally share links. One less copy and paste procedure. I can't imagine it would hurt though. When I left Digg it was in large part because Reddit was set up with all the group social media buttons that Digg had. Something to work on down the line. I contacted them a few months ago and I don't think I heard back. It's just a plug in or add on for Firefox browser.
